do you need the mouse? if not, you should tell pygame not to listen to it. if so, you can mess with .pump() or turn off the mouse input until you need to listen for it.Hi, I've a big problem, happenig on all the PCs I've tried. If I move the mouse several times, often happens that keybaord input seems to be blocked. In particular the function pygame.event.get() doesn't receive any event. hints?
